<p>An electrical connection across a peripheral surface through a sealed enclosure (34A) in a radial plane between a tubing hanger (5) and a surrounding support member (3). The connection involves a coupling element (17) in the tubing hanger and a shuttle (20) which can reciprocate from a position wholly within the support member, across the interface and into electrical connection with the coupling element, without producing any movement of a cable (9,10,11,15) leading into a sealed enclosure within the support. <IMAGE></p> |
